Design and Operation of Water Disinfections Plants
 Krupicová, Simona ; Rajnochová, Markéta (referee) ; Kučera, Tomáš (advisor)
In the first part of my bachelor thesis I deal with individual disinfectants used for hygienic supply of drinking water based on chlorine and without chlorine. Then I mention the operation without chlorine disinfectants. In the second part of this thesis I describe individual plants using various disinfection methods and at the end of the thesis I compare these methods and use it in practice.

Haloacetic acids in drinking water
 Poslušná, Markéta ; Načeradská, Jana (advisor) ; Barešová, Magdalena (referee)
Chlorination byproduct occur during water disinfection. These by-product are formed by the reactions between disinfectants and natural organic matter. High concentration od natural organic matter require higher doses of oxidizing agent, which increases the formation of chlorination byproduct. Chlorination byproduct pose health risk so they must be eliminated. This work researches focuses on the occurence of chlorination byproduct in several countries and evaluates the suitability of limits concentrations. The literary research has shown that there are currently not many studies about monitoring the occurence of chlorination byproduct. If these studies exist, they are often old and therefore i tis not possible to rationally assess the quality of drinking water in term of the occurrence of chlorination byproduct. Trichloracetic acid, dichloracetit acid and dibromacetic acid are mainly important from the health point of view. The are identifield as possible carcinogens. Higher concentrations of dichloracetic acid and trichloracetic acid were observed in most studies. The result of the studies show that the highest concentration of haloacetic acid were recorded in the cities of Cherepovets (Rusia), Athens (Greece), Warsaw (Poland) and Findland. Concentrations of haloacetic acid did not exceed the limit...
